Thank you for choosing this Drum Sander. We are pleased to offer you our best machinery and service, and trust that you will find our machinery economical, productive and easy to operate. This manual covers the proper operation, safety and maintenance of the machine. It is important that this manual be read in its entirety before operating the machine. Although the machine has been checked and inspected in compliance with relevant safety regulations, the machine's safety and best performance are dependent on proper maintenance and operation. Hazards that arise due to improper operation and maintenance are solely the responsibility of the operator. We thank you again for you choice, and for your careful reading of this manual. There is a certain amount of hazard involved with the use of woodworking machinery. Using the machine with the respect and caution demanded as far as safety precautions are concerned will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, severe personal injury to the operator can occur. 1. Read the operation manual before operating this machine. 2. The machine should be disconnected from the power source before performing maintenance

or adjustments to the internal mechanisms, or when making repairs.

3. Before leaving the machine, make sure the work area is clean. 4. Check timber for loose knots, nails, or other items which may cause a hazard or affect the

machine's performance.

5. Keep all guards in place and in working order. 6. Do not force the machine. It will do the job better and be safer working at the rate for which it

was designed.

7. All children and visitors should be kept a safe distance from the working area. 8. The operator should keep proper footing and balance at all times. 9. Do not operate the machine while under the influence of drugs, alcohol, or any other

medication.

10. Avoid awkward operations and hand positions where a sudden slip could cause your hand to move into the sanding drum.

11. Never leave the machine until it comes to a complete stop, and never leave the machine running unattended.

12. The employer is responsible for selecting competent and qualified employees. 13. Safety shoes should be worn to provide protection against rolling objects, falling objects, and

sharp edges in the workplace.

14. Eye protection should be worn and such devices should be carefully selected, fitted and used. Compulsory wearing of glasses with impact resistant lenses and side shields is a good safety

policy.

15. Wear hearing protection when operating the machine. 16. Do not wear rings, necklaces or jewelry around moving machinery. 17. Do not wear loose fitting clothes. Clothing should be comfortable, but long sleeves, neckties,

etc. should not be worn.

18. Do not wear gloves or other hand covering articles around moving machinery. 19. Cover long hair with a hair net or cap. 20. Protective guards and shields must be in place at all times unless they must be removed for

specific service or maintenance. They should be immediately replaced when service or

maintenance is completed.

21. Make sure that operator clearly knows how to stop the machine before starting work. 22. Never clean or remove chips while the machine is running. 23. Do not alter or remove guards and warning labels. 24. Keep the immediate area clean. Do not allow the floor to become slippery, or covered with

dust or obstacles. Dust that accumulates in the work area is a hazard that can cause you to

fall or slip against the machine or its controls.

This Sander is rated for voltage and amperage appropriate to the area where it is sold. Confirm that the electrical specifications match your setup before use. Proper grounding is essential. Failure to properly ground the machine may result in electrical shock and injury to the operator or other personnel. If the machine is to be used with other electrical configurations, all connections must be made by qualified service personnel, and the setup must comply with local codes and ordinances. Use of an extension cord is not recommended. If an extension cord must be used, it must be of adequate size and capacity to support the amperage and distance between the machine and the power source.

WARNING All electrical connections must be done by qualified service personnel! Failure to comply may result in serious injury and/or damage to the machine! The machine is provided with two 4-inch dust chutes. Use ring clamps to attach dust collection hoses to the chutes.

WARNING Do not operate this machine without a dust collector attached and running.

Removing the Sanding Belt Lift the upper guard and tilt it to the rear, in order to access the sanding drum. The sanding belt is fixed at either end of the drum by spring loaded clamps. To remove the sanding belt, push the right clamp forward and pull the tab of the sanding belt out of the right drum slot. Unwind the sanding belt from the drum, and push the clamp forward at the left side of the drum to remove the sanding belt tab from the left drum slot. Mounting a New Sanding Belt Insert the tab of the belt on the left end of the drum, and push the left clamp forward so that the tab will slide under the clamp. Releasing the clamp will lock belt tab into place. Roll the sanding belt onto the drum, keeping the edges snug. Tuck the tab at the right end of the sanding belt into the slot at the other end of the drum, pushing the clamp forward so that the tab will slide in. The clamps are spring loaded, and will hold the belt increasingly tightly as the drum revolves. Replace and mount sanding belt on both sanding drum by this method.

CAUTION Make sure the machine is disconnected from the power source before mounting the sanding belt.

MOUNTING AND REPLACING SANDING BELT

10

If the conveyor belt runs to the right or left during operation, or the conveyor belt tension is too loose or too tight, adjust it by turning the adjustment nuts on either side of the conveyor table. The conveyor belt should run at the center of the conveyor table, and should be tensioned so that there is good traction during stock feeding.

The drum is driven by one belt and powered by the main motor. If the belt become too loose, remove the right end guard, front guard, and then adjust the position of the motor (height) by turning the M12 nuts on the height adjustment bolts (See figure). (for model DS-25 26 38038A 13 13A)

If the motor becomes damaged and needs to be replaced, remove the bolts on the bottom of the motor base plate, and remove the entire motor assembly.

The drum is driven by one belt and powered by the main motor. If the belt become too loose, remove the right end guard, front guard, and then adjust the position of the motor (height) by turning the M12 nuts on the height adjustment bolts (See figure). (for model DS-25A 26A)

If the motor becomes damaged and needs to be replaced, remove the bolts on the bottom of the motor base plate, and remove the entire motor assembly. If the conveyor belt becomes too worn, the workpiece will not be fed effectively. To replace the conveyor belt, remove the guards at both ends of the sander, and remove the four fix screws at the bottom of the feed table assembly. The feed table can then be removed so that the feed belt can be replaced. (see figure)

Start the dust collector before turning on the sander. To start the machine, press the green 'ON' button on the control box. Turn the key switch to start the conveyor belt running. Turn the conveyor speed adjustment knob to the desired stock feeding speed. To stop the machine, press the red 'OFF' button on the control box. Use the crank handle to set the sanding height to the desired thickness. If the thickness is not known, place the workpiece on the table, where under the sanding drums, and then raise the conveyor table until the sanding drums reach the workpiece. The thickness can be read on the depth gauge located on the front left of the machine. When feeding the workpiece, place it at the center of the conveyor belt. There is centering gauge on the infeed side of the machine frame that indicates the center of the conveyor belt. The maximum workpiece thickness acceptable for this machine is 5". The minimum workpiece thickness is 1/4". Do not attempt to sand workpieces outside of these specifications.

NOTE Before performing any maintenance or lubrication, disconnect the machine from the power source. 1. The table height adjustment screw shafts located at either end of the machine must be well

lubricated with grease. 2. Make sure all nuts and screws are tight before sanding. Check that the sanding belt is

mounted properly, and have not become loose or torn. 3. Do not allow excessive dust to accumulate on or in the machine.
